Requested by Nefarious Seraph 13- thank you

Byakuya, Karin and Ichigo x Rukia

Errr… assume that Ichigo has told everything about the Soul Society to Karin. Or that she has forced it out of him. I guess either is plausible…

Integration

The act of integration is the act of incorporating separate groups of society into each other. However, in the case of poor Ichigo Kurosaki and Rukia Kuchiki, integrating their families was proving to be a monstrously difficult task.

Ichigo slammed the living room door shut behind him, throwing his body weight against it in case the full force of Byakuya's irritation was able to push it open behind him.

And he thought family events were meant to be fun.

"You know, you're going to have to go back in there sometime, Ichigo."

He glared at Rukia, who was watching him, a tray of drinks in her hands, with a raised eyebrow. He took his drink off her, swallowing it quickly, cursing provenance that he had to get with a girl that had such uncompromising, terrifying family.

"It's a good job you're hot, that's all I'm saying. If you weren't, this totally wouldn't be worth it."

Inside the room, more glares were being shared. Karin was not best pleased to be left alone with the man who looked like he had a stick shoved up his ass.

"I'm only doing this because Ichigo asked me to. Don't expect me to exchange pleasantries."

Byakuya crossed one leg elegantly over the other as Karin folded her arms.

"That is good to know. It appears that all of the Kurosaki children are as ill-bred and foul-tempered at their incompetent older brother."

If he thought he could rile Karin that easily, he obviously knew nothing about the years she had put up with her father. Her father who, thanks to a well-timed birthday gift, was currently far, far away from ever meeting the stoic, disapproving shinigami who now sat, entirely out of place, in the Kurosaki front room.

"Heh. If he's so incompetent, what does that make you? He beat you."

A muscle twitched in Byakuya's eyebrow.

"He had luck on his side."

"Luck ain't anything to do with it."

Byakuya wondered if Ichigo would kill him if he murdered the boy's sister. He supposed, judging from what his own reaction to the sight of Rukia's body would be, he would.

And it would probably be painful.

"Besides, at least Ichigo doesn't have a fruity, flowery zanpakuto. What the hell is that, anyway?"

From behind the door, Ichigo suppressed a laugh.

"That's my girl."
